Things to check in Derby

Noise

Outdoor unit noise is designed in from the start, not fixed afterwards.

Conservation areas

Historic streets and listed buildings in and around Derby are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

Diversity

Not every room peaks at once; good design accounts for diversity so central plant is not oversized.

Roof and height work

Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.

Types of premises we cover in Derby

Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
